Hi, this is my first post here. Nice forum! Sorry for my poor english, my native language is spanish. This is my question. I have a 60 white led fairy strip, from a solar-powered led christmas rope. This rope were powered by one nimh AA rechargeable battery, feeded by a small solar panel. This panel were damaged, so i throw it out and tried to reuse the led strip powered from mains. I connected the strip to a 3v power supply, without adding any resistor. All the leds turn on, are bright enough and don't seem to become warm. So, the question is: is safe this circuit? it will last for a reasonable time or the leds will have a short life? Do I need to add a resistor?
